The store also sells feeder fish called "Rosies".
At about 12 cents each, how can I go wrong. I purchased 5. Each was
about a bit less the 3/4 inch long. Into the tank they went. At
first
Nelson didn't quite know what to make of them. Two days those Rosies
swam happily, but on the third morning, all gone. I believe he
discovered their tastiness at night when they were dormant and easy to
catch. A real carnivora he's become. He also relishes small
earthworms and slugs. Where will it end?

Careful. Feeders can bring disease into the tank.

Might want to do a risk of bacterial infection vs amusement tradeoff...
